I have considered them ... Aaron Wilson starts his 90 inch S&S engine with a heavy duty starter although he has had a few crap out on him ... I will try to go without compression release initially and see how it goes ... on the fueler I always used rollers but it was a pain in the a-s.

Joe,

      FWIW, I have been using the stock starter on my Buell from the very get go. I believe the compression is somewhere of the neighborhood of 13.5-1 and I have never had any trouble at all starting the bike, not once. I have been using a Big Boar (BB)battery for the bike since day one as well, these batteries are bullet proof! I had a long and low rigid chopper a few years back that had a 113" motor in it with compression releases and I think that bike ate every battery I ever put in it until I went with the BB. I have left the iginition on and drained it completely, after recharging it was good as new, it has been subjected to about 30 + dyno passes, 8-10 passes at El Mirage and 5 passes at Bonneville, I have accidently drilled a hole into it and it just keeps on ticking! This is the second BB battery I have owned and I will never buy another brand for a rigid Harley. Rchop can back me on all the problems I had with batteries and how the BB solved them.

Scott,
I am using the stock starter in 60 cu in bike with 13 to 1 and it is fine ... I will go with your suggestion on the battery and see what happens. I am going to build a set of rollers just in case. Can't hurt and someone may need them at a meet.

This summer we put an S&S 124 engine in a street Harley Fatboy. They come with 2 electronic compression releases on them. It starts right up with a stock starter & battery and has been trouble free so far. Maybe something like that might work, just thought id mention it. When you turn the igntion on you can hear them click on.

Joe,
The only time we killed starters on the 100" bike was when we were starting it on a 50/50 Nitro blend. Once we put the second tank on it so we could start it on pure methanol we have had no problems.  Our 1350 cc bikes have zero starter issues.

I will have to agree with Scott, I had a Big Boar battery in my last LSR bike and will haveone in the new one. No troubles at all.

Feeling a bit better tonight ... I can get around the garage a little ... It is good to have a friend that owns a machine shop and likes racing ... my friend John was looking a damper mount that I had on the 1000cc bike and he asked if I needed one for the new bike ... I was going to buy 2 from Storz as I plan on using 2 dampers ...  he insisted on making them ...

He also made me a sprocket spacer and in typical fashion he insisted on adding the shoulder the the center hole rests on ...

Finally recovered from the recent unpleasantness and I am able to work in the shop. Roughing out the seat pan.

Today I plan on setting up the rear sets ... I picked up a really nice set from an R6 Yamaha made by Attack ... Just can't get them to fit without chopping the hell out of them ... I would rather fab up my own and sell the R6's ... shame they are really well made.

I may have to take a week off from work ... I will be ready mechanically ... no fairings and may not be painted pretty but I will make a pass in April.

I keep running into unexpected delays, imagine that :roll:.  I'm not gonna be ready, but I'm going anyway. I'll probably help with tech inspection.
