I have a 150 (202) built with the assistance from Powroll. They are very nice to work with and very honest.
Let me just list the mods. This bike is a monster!!!!! And very reliable

Powroll Crank Stroked 9.5mm
Powroll Cam
Powroll Exhaust
Powroll 170 Kit
2004 CR85 28MM Carb
Carb insulator (Rubber intake) from a CRF 230.
Ported and polished head
Tag T-2 1 1/8" Bars with clamp adaptersBars
BBr CDI Box
BBR Rear Spring
Custom made fork dampeners and spring set up
K&N Filters
520 NON "O" Ring Chain (Not a cheap 428 Kit)


You must note that this bike will NOT I repeat Not start on any kind of pump gas. It will not even run on Ultimate 4 Race fuel. WE run Race Gas at about 110 octane. I am getting ready to install Burnett Clutch plates in the bike. This thing like to eat plates now. I wonder why. This was not cheap to do but just to let you all now that it is possible. Have not DYNO'ed it yet but I think we are over 30HP.

One thing I have found out is that the 175 Kits out there are not safe. The cylinder wall thickness is under minimum. You must resleeve the Cylinder. If you are going to go that far, you can resleeve with a 69.5 mm Piston and get 187cc from the stock stroke and 223cc from the powroll 9.5mm stroker and this is safe. But then again this is not for everyone. It is expensive. I think the 223 will be my next project, I have two of these 150's.

Just remember "Be Safe and Ride it like you stole it"
Most of all Just have fun
I will answer any questions and have some pics

Thanks

I loaded some pics and here is some more info about the bike. Some things I forgot on the first post.

Complete exhaust is wrapped in 2" wide headed wrap. This is the best mod you can make. It keeps the exhaust hot and the gas flows better. The bike has the Powroll exhaust. Only because it is a wild mod motor. Believe it or not if you take the spark arrestor out and replace it with a tip. IE: Powroll's exhaust tip, a stock or slightly modified motor will flow better than the high priced exhaust sytems. Bottom line-- If you motor is not highly modified you do not need an aftermarket exhaust. Just the 1 1/4" header will do you just fine. I hate to see people waste money.

Everyone need to go to the Powroll site. They have even done something that no other site has done. They actually have posted carb needle and jet info for you to see. Did BBR? No.....That is one reason why I like Powroll.

As you can see in the pictures we have done a lot of custom work on the bike. And no I didn't spend the $3000 on CR 85 forks. Not needed--FORK BRACE that is all that this bike needs. $70.00 - $100.00
Another thing Alumunium top Clamp-- Why spend the $100.00 - $250.00? If anyone know an advantage to this please let me know.

No I don't work for Powroll and I am just an old street racer from the 70's and 80's. This is my son's first bike, I am trying to teach him "old School" and it is working.

When we started doing this we called all kinds of manufacturers and got the standard answer. "Buy our stuff, it is the best." Well sad news - The best is the cheapest most of the time.

I really hate it when people lie to sell items. That is why we did ths bike. To prove that if you search the internet and ask the right questions (CR 85 Carb $50.00, Ebay, 5 min mod.in garage and it takes the same jets as the PD 24mm stock) $50.00 VS BBR $299.00 or even Powroll's 26mm for I think $399.00.

Want any more secrets just ask. Ask the right questions and be smart and your dollr will go far.

Thanks

in your last post you said that all you needed are fork braces instead of cr85 forks. I was wondering where i can get some of those

[normb359]

First thing I would do is install BBR front springs. This helps alot.

The fork brace will not give you the same support as the CR85 Forks. However it will be in my opinion 100% better than stock. I have talked with alot of people and they all say that if you do enduro of even motocross you should get a brace. I found one on E-bay (about $70.00). If you go to Superbrace.com, they have a good interactive page on how the brace works. They do not have one for the CRF150 though.

Let me try to explain how I modified the forks on my two bikes.---

I do not recommend this to everyone. You will need a mig welder and a drill press. Do this at your own risk.

These forks have dampening rods in them. The rods have bleed holes in the bottom. These rods are steel. The holes are 11/64" diameter. By trial and error I have found out that a 150lb rider needs a 7/64" hole. A 200 lb rider needs a 9/64" hole. What is my basis--My son is 140 and I am 200. I just welded the holes and ground them smooth and redrilled. We blew seals on the bike I ride and not my sons. So I redrilled mine to 9/64's and no more problems. I use the factory amount of oil, but I use 30 wt motor oil. Both bikes have been ridden all summer and no problems.

If you do decide to try this I highly recommend you purchase new dampening rods first. Install the screw on the bottom and then weld. The screw will keep the rod from warping too much, preventing installation later. I can attest to this from experience, been there and ruined one ....

Hope this helps and good luck

I forgot to mention. I don't think you are going to out ride this bike, to warrent CR85 Forks. If you have looked at the pictures in my album, you will see want I mean. We almost abuse that two bike we have. And the most we have done is scratch plastics.

I have heard stories about broken frames-- But no proof of that as of yet. About one time a month we actually give these bikes a good inspection, because of the riding we do. No problems yet.

[Toneconsultant]

Dude. Duuuuuude!!!!! I must say, nice motor work. I, however, believe you better address your suspension or it won't matter how much power you have. Check out my weblink "http://toneconsultsant.tripod.com.

I have to update it, but you really need to can those BBR springs and put some time into your suspension. I did CR80 forks and revalved my stock shock (Yes, it can be done) and let me tell you, once that's done, you knock off about 8 or 9 seconds off any tracks lap time. Yes, it's that big of a difference. The rear shock is the key. Get it revalved.

[normb359]

Hey Tone---

Here is one for you-

I think we are going to do CR125 forks on the monster.

We have checked and we have access to a press and center guide for the steering stem if needed. I think Race Tech can do the spring lowering. You only need to lower them about 2". We are going to pick up a CR125 front end in the morning (1 Jan 05). Also I am being told that a 2001 and newer CR125 shock has about 15.5 - 16" of travel. So It may work on the rear of the 150. I will let you know. Looked at your bike. Looks good. Where did you have the rear shock done. Just in case we need to get ours done.

Thanks

BTW if the 125 fork thing won't work I am going to look at RM110 Forks. I found out they are 40mm. Who knows????????

[Toneconsultant]

You know. I better head off someone's next comment, which is, "Why would you put so much time and $$$ into that trail bike?"

Well, because we can and most of all, it's fun to fiddle with!!!

CR125 forks? Wow! That sounds big. If they will work though, that would be sort of neat. I just hope they will work. I question it because you might have to fiddle with getting the wheel on there. I'm talking about spacers and stuff like that. If it works though, then you'll be able to dial those in much better than CR80 forks.

As for revalving my rear shock, I don't have the number off hand, but call Campbell, CA. and ask for Hlebo's Suspension. Tell John that Langley sent you over. Trust me. Just doing that shock will make your front end work awesome! Really. The shock is so much better that everyone works better.

[Toneconsultant]

P.S. I almost forgot. As for the CR125 shock, I don't think it will fit, but if it does, you'll have to give me a full report.

Putting the 125 parts on that bike might be a bit much, but trying it is sort of half the fun.

[normb359]

I am going to go with the CR80/85 forks right now. But we do have a 125 set-up.

Yes you are right. "Because we can" But this kind of modification is not for everyone. It is EXPENSIVE. We happen to have a "machine shop" at our disposal. We also have done many hours of research. And countless distroyed parts. The most fun is just the idea of "Can we do......." "Well--Let's try"

[normb359]

BTW the 125 froks are only 2.25" longer than the CRF 150 forks. We just have to figure out the wheel mounting whojiggy thingamabobs.

LOL
