THIS TIME ITS A DRAGBIKE

well a friend of mine came over monday and we shimed the valves that went very good took some time but no problem :woohoo: now it is tuesday so the cam guy came down and we started getting that job done i was pretty fired up about getting this done felt like this build was about to come to a end. (well not) as i had thought we got it all put togeather and was checking the clearences bigger than shit the ex. valve touched the piston :sick: witch dont surprise me because nothing has gone smooth on this motor from day one so we are back to the pistons hanging out of the cases. seems that the person that i got the block off of has decked the block. the pistons stick out of them about 35-40 thous. so what i need is a spacer that is about 80 thous. is what i was told to be safe the problem is i spent about a hour an half trying to find one but cant find one that will fit my motor i have to call fast by gast this morning on there web site they say that they make custom ones, hope so.if anyone knows where to get a 80 thous. thick 3.210 bore for it would be great ( you got to love this stuff )

called fast by gast they didnt have what i need so they told me to contact cometic and i did, they are going to make me one for what i need $37.00 man you cant bitch about that and they are in ohio hope this works...

Here's your photo cropped and resized..... The proud piston is easy to see.

IMO, the way to go is get the valve reliefs cut deeper on the pistons and shoot for zero deck with the spacer.

I ran into a situation where J pistons & big block were used with a heavily shaved KZ head. The intake valves touched the edge of the valve pocket where the red arrow is pointing.

before ordering that shim for cylinder base id have that cylinder checked to make sure itsw flat top/bottem if not id fix that to make sure youre getting the right shim.

well there has been alot going on around here havent been getting much done but i did get the chain on had to have a couple of spacers made to center the wheel. got the chain gaurd on also. i mounted the air tank and the shift valve.got the spacer for the motor and had the block checked for true everything is fine



got another set of coils & wires i had to rob peter to pay paul one of them went out on the orange bike so i took them off of this one so needed another set

also found a set of cam motion z4 cams i am looking into but i wont put them in till winter i just want to get this thing running my friend is coming this week to put it back togeather and i wont have the z4 till next week so that will be later. hope to see some of you guys at vintage this weekend going to be there sat. have weekend pass so mite be there sund. also dont have anything to sell just like to see what everyone else have.

Just noticed your front end isn't raked, be sure your front stem bearings are set right and run dual stabilizers. With the power your going to make you will mph out the back at more speed than these things handle well at and it is a real problem with these bikes.
Progress is progress! Still looking good!

les the frt is racked the pic is just not showing it



i have one stablizer on it do you think it would be better with 2

I see it now, who ever done it did a nice job by the look of it! Just looking at it I'd guess from 7 to 10 deg. I'd say 1 is fine and I believe most tracks require at least 1. I've made a few speed runs on mine and at 5 deg with no stabilizer it's real stable.
Are you going to run a dot tire or slick with struts? I've read where a street tire isn't happy on struts, have a hard time keeping them hooked after launch.

Les

les --- it does have struts with caster mgts. it has a shinko with the softest compound on it these new tires hook very hard. i do have a 18" wheel with a slick on it but i dont like the rim that it is on it is a old ninja wheel so i am going to stick with the one that is on it for now.

I've been 148 mph with stock frame and 1 stabilizer with no problems at all...66" wheelbase though.
