At my last race I busted 3rd gear into pieces and knocked some teeth off of second. I was running a pretty high gear (14/42).  Is there optional gears out there that are stronger for the peerless? If so what are there part numbers and how to tell them apart?

I have been using a TinyTach the last few years on my mower but would like something a little nicer but I don't need or want EGT or cylinder head temp. If I combine this http://www.amazon.com/Baron-Custom-Accessories-Tachometer-BA-7315-50/dp/B001KO17TS tach adapter with this http://www.amazon.com/Longacre-44402-Digital-Tachometer/dp/B005JVEBZU/ref=pd_rhf_dp_p_img_4?ie=UTF8&refRID=0H34GEVE4DGK6RKND4KN tach set for a four cylinder engine would it work? I have an Intek V-twin.

I am building a 44 Intek with some used Ryker heads with an unknown amount of milling.  The previous owner of the heads ran 108 octane on a 40ci. He claimed it did not run right on premium gas. There was no mention of knocking or pre detonation but if it did knock it should have snapped his stock 40 rods like a twig.  I would like to run 93 octane because I am cheap and believe when the rules say pump gas they mean everyday regular premium not race gas.  So how much compression can I run on 93 and was the previous owners problems with it just a matter of tuning? 

Does anybody know where I might find some quality high speed bearing with a 3/4" inside diameter that will fit  hubs standard front kart hubs? I found some for a hand cart that would fit but I would not trust them to last very long.

I purchased a 1979 John Deere 65 off of ebay a few years ago with intentions of making a racer out of it and now I am finally getting to it. I got it tore down to a bare frame and started cutting excess brackets and metal off it.

 
 
I have a few things that are worrying me about the build at the moment. The engine crank shaft and rear axle are going to be in real close proximity to each other. With some rough measurements the 13X6.50-6 Turf savers I plan on running will put the rear axle right in the middle of the 4" tall frame with the frame 4" off the ground. Because of this I will have to run the engine drive pulley under the rear axle about 3" down the crank shaft from the bottom of the engine. I will also have to lower the trans to line up the belt but that is a good thing because it will give me more room to lower the seat after I give the engine a 90* turn to the left. Do you guys think the pulley sitting that far out on the end of the crank shaft will cause any issues?
