99 WR400..... It has been sitting for a while and i wanted to start it... About a week and a half ago, I went outside and started it on the first kick. ran it for about 2 minutes, and it stalled shortly after i took the choke off. I didnt try to restart it after that. The next day I tried to start it again, but couldnt get it to start after about 10 minutes of trying. Yesterday i went at it again, but with some starting fluid. I sprayed some in the airbox, set the seat on it, and tried to start it... still no go. I then held in the decomp and kicked it through a few times and after about the third time, it backfired very loudly and the air filter cought on fire. I poured some water on it to put it out. fortunatly, the only thing that was hurt was the air filter, nothing else got burnt. my problem is that now there seems to be little compression. there is very noticable resistance, but i can push past tdc with my hand. I can hear air slowly seeping through somewhere although im not sure where. what could have cause my no start, and now my low compression problems? Thanks for any help.
