Been busy with work. Will address the questions tomorrow.

I appreciate the responses. The chain was just rest so I could make sure my pin count was correct and my arrow was at gasket surface. The holes in the piston were from the adjuster screw wandering. Also no markings on cam ends. I’ll have to do some measuring. I’m going to spray nitrous until I get an acceptable time out of this piggy.

Some interesting stuff going on in # 3. Adjuster screw decided to go on a journey.

NW suburbs is where I live . 1/4 racing at a small track in Wisconsin. Been playing with bikes for 50 years. Bought this one in Texas. Sold the previous one to the old guy in the picture. Working on making this one faster. I’ll read the rules in just a minute...

All I can tell you is I went to adjust the valves and found 3 adjuster screws in the cam valley. The problem was 4 were missing. I dropped the oil pan, fished around in the cam chain valley and never found the screw. Piston #3 sure looks like it was bouncing around and imbedded it in the top of the piston. Anyway... the damn thing is too slow. I'm collecting the parts to put a 10 bottle and monster jets and see how fast I can go before it goes boom.I think the frame is good for 8.50s. Turning down launch rpm so I don't spin the tire. The previous owner said he got 1.12 60 foots out of this with 250 horse power. He has told me a couple fibs before...But a nice guy.
