fixitrod Posted April 4, 2005 Report Share Posted April 4, 2005 You could have caused some damage with heat. You've gotten lucky so far with running pump gas but you could have a number of problems. Crank Seal plug wire (swap the plug wires. They fire at the same time anyway, you can't get them backwards. If it's smoking white, it could be a head gasket.

rocketboy Posted April 4, 2005 Report Share Posted April 4, 2005 look at your plugs ,do you see little gray or white flecks on any of it? sounds like your bikes detonating from running pump gas ,you will DEFINITLY need 100+octane if it were me and your bike isnt ported id run another base gasket ,this will raise port timing slightly and drop you down around 155 psi which is safe for premium and youll notice alittle faster and higher revs too.IMO Quote Link to comment Share on other sites More sharing options...

If you want to diagnose more first you can try a leak down test to make sure you do not have an airleak. All you need is a torque wrench and a head gasket. If you odn't have the wrench nowis as good a time as any to buy one. I got mine from Harbor freight for $20 and it does the trick. if you do the leakdown test and you have a coolant leak it will more than likely pressurize the coolant in the radiator.

ssanddemon Posted April 6, 2005 Report Share Posted April 6, 2005 (edited) I had a similar problem and it ended up being the crank seal. Like a dipshit, I put it in backward when I had the motor apart for crank welding. Ran great for two years of hard use, then it sat for 6 mos. Ran like crap after that. I think it had been edgy but still sealing, then started leaking because it had dried out from sitting. Pain in the ass to replace if you don't have the cases split.
