wow man you need to get a biger carb to let that thing breath. for that bore and im assuming that your going to ice race it. i would say get a Keihin 39mm PWK carb. it would really let that motor breath.

[RumbleB]

Lol no. A bigger carb might be good if I was just going for top end power on the ice. I want nice usable power for the trails. The low end would be a dog with big venturis.


Mudlites!

Oh yeeah. No more traction problems for you man! They look great on there.

[RumbleB]

Thanks PB. I know I went against most other's advice on tires, but the voice in my head keeps reminding me of all the muddy crap I used to go through in New England where I would have killed for a set of mud tires.

Oh and it is geared low enough to handle 22's. I found a guy on ebay that sold me an abnormally big rear sprocket, and the front is a 12 tooth.

a cr80 uses a 28mm keihin carb ...belive me your choking your engine for sure ,you wil l get power everywhere not just topend although it wil lhelp that a great deal ,if your concerned about going big o nthe size size atleast update to a better modern carb like a 33mm pwk ,even a mild 195cc blaster can run good o n that 35mm pwk

[fastR of puppets]

ya a stock blaster is choked a bit on the stock 26, so the absolute smallest i would use on that would be like 32-34, on my stock R engine i used to have a 36mm and i had PLENTY of torque

[Paulie B]

Mine came from he factory with a 38 and it was 80cc's smaller then your monter. It had hella torque. I still use a 38mm and the torque almost pulls my arms outah socket right off idle. Believe me if you wanted you could get at least a 35mm.

[fastR of puppets]

ya your probly losing torque since the motor is so starved

[RumbleB]

Sorry people. It seems there's some confusion here. The model number is PJ26C, not the carb size . I'm pretty sure it's a 38mm carb, but I don't have the manual in front of me. The carbs on my RZ350 are 26mm and much smaller.

EDIT: I have the manuals in front of me. Stock carb on an 83 CR480 is PE45C (38mm) and stock carb on an 89 CR250 is PJ26C (38mm) Actually all the carbs on 88-91 CR250's and CR500's are 38mm.

[fastR of puppets]

it doesnt look like a 38mm
