Vintage Dirt Bike Q & A

Whats the difference are they just lighter? Also if you us a front wheel from a cr mr is the spedo still gonna be able to be used? Planning on using my mt for the street and some trail riding its gonna have the cr setup top end crank rotor reed valve ect. so I was wondering if anyone has any experience with the aftermarket pipes available and could tell me what one is best for the street. I am kinda leaning toward the circle f pipes as I read they are good throught the rpm range but cant find any info on the dg pipes.

Wheels are just lighter, but they are unsprung weight, so they allegedly help more than you'd think. You can probably use the speedo if you use the MR hub on the front. Can't use the speedo if you use a CR hub on the front.

might give jemco a call.i hve one of their pipes on my mt.its pretty quiet and makes decent power.

i got this pipe back in 92 or so and it was at the time sold through krause racing.
