Engine and Bottom End / pro-x 350 engine vibration?

« on: January 03, 2016, 10:02:25 AM »

i have a 350 (78mm piston) pro-x jug i put on a 86 motor.  the motor seems to have quite a bit of vibration through all rpm.  all of the dots where lined up when the motor was assembled.  i had a machined aluminum balancer cap that i had picked up in a pile of parts somewhere down the line that i put in as well.  the bearings seemed good on both ends.  is there something a guy can do to help, or is this just the nature of the beast with the big bores and heavier than stock pistons. thanks

Engine and Bottom End / bore size ?

« on: January 21, 2014, 05:01:59 PM »

on a 86 jug with the extra thick sleeve installed with the stock 86 length rod, what is the max bore on these?  i have seen pistons up to 69.5, but i thought i have seen builds with a 72mm bore on a stock looking jug.  is that right?  and if so, what pistons are they using?  thanks

« on: December 21, 2013, 02:31:26 PM »

i have been accumulating parts for an ignition setup on my 86r.  right know i have a mildly ported factory jug, fmf gold pipe/silencer, with a v3 reed cage, k&n air filter.  i will be updating soon to a 38 mm as with a ported 350 prox jug.  right know i have a 2001 cr250 flywheel and coil, and a 2001 cr125 cdi.  i need to get a stator setup with the adapter plate.  i would like to use one that i can run lights with.  what is the best way/options to do this? it will be for trail and wood riding with buddies.  thanks
