bike has me almost getting devorced...need help

No but seriously....i just bought someone else's problem...my luck
i was stopped at the light bike running fine then changed pitch to a lower sound (tone) almost stalled when i went to take off...like it had no balls...first thing i did was a compression check ...pushing 60psi all 4..did a leak down 2 & 4 where questionable but were still within range..then did a valve clearance and those were all within spec as well...what else could it be ? anybody

ID probably just start by giving it a service, oil filters and plugs - and while I was in doing those things, its a good opportunity to see what state the bike is n under the body work. plugs might even fix your issue.

If it's got tits, or tyres, It needs to be ridden hard.

so having fouled plugs can cause it to have low compression?

Why didn't you just buy some new spark plugs?

My apologies, but it sounds like you need to take it to someone who knows what they are doing before you ruin it...

compression could be rings, or valves not sealing which can be caused by several things.

dont clean spark plugs, just replace them.

if its knocking, its time to seek professional help if you arent competent yourself with pulling engines apart

If it's got tits, or tyres, It needs to be ridden hard.

I found a spec on our site for your reference.

sounds like someone sold you a bike with a bad engine.

First time rider over 40. Finally made it!
