Slight Bog.

Postby 600xcr » January 12th, 2004, 4:09 am

I've got a 95 xcr 600 and when i am sitting at a dead stop and punch the throttle to the bar it seems like it hesitates for a split second and then takes off. I kept getting wasted out of the hole this weekend by and xlt but then i would hang right with him. is it something to do with to motor or a clutching issue.

Thanks in advance!

it could be old gas left over from last season, throw some octane boost are a splash of racing fuel in and see what happens

I would say check your clutches, maybe clean out the secondary.

hold the throttle at a constant rpm that is a little before where the clutch engauges, and them nail it. If it still boggs I would say clean the carbs out really well

i'd say check your belt if its really shiney on the sides that could cause it to slip and bog for a second or mabey there are wear spots on your belt, it happend to me i thought my clutch was F***ed but i swaped belts and it accelerated like its supposed to.

I would start with that carbs. If there is a bog i'm guessing it would be gas related as a belt slipping should not effect engine speed like too much or too little fuel. Everytime I have experienced bogging I traced it back to the carbs.

The other alternative would be weak primary or secondary springs. Too low of an engagement with not allow the engine to reach a more powerful rpm and if the secondary is opening to fast the gear ratio will be way off.

My two cents

Sounds like you have too much belt deflection or an aftermarket belt will do this also. I proove people wrong all the time on this problem. Good luck.

Just a note i have been told you should not run those octane boosts in 2 strokes because they limit the oils ability to stick to the engine's internal surfaces

clean your pilot jets first to eliminate that problem and then look elsewhere

I just recently had a similiar problem with my machine and it turned out there was a peice of debris blocking the main jet in one of my carbs. Strong argument for draining them every season.
