Good info. Except the fact that it was a bone stock engine. Now it has high compression pistons that are forged. And I was cruising at about 60 mile an hour on the interstate in light traffic When it happened. so I’m genuinely curious on your response to that

Motor is done. 81 mm bore, 1216 cc. 11.2 to 1 compression. Well the head was off we redid the valves. Made sure everything was good. Cleaned up real nice. Trying to figure out jetting. I will be doing a lot of trips to sea level and although I live at 7900 feet elevation. I think I would rather have it jetted for sea level. Trying to get this thing dialed in for long road trips. Nice thing with the tub as I can Carry a tent, a cot, sleeping bag, nice size cooler. And all the goodies

I would think it would be better to be fat. Then to be Way lean

Late last year I punched a hole in a piston. Still don’t know why. I Bought a Dale Walker /J&E Holeshot performance 81mm/1216cc kit. This rig is built for long trips. And although I live at altitude. I will be doing a lot of sea level riding. So I want to jet it for sea level. Anybody have a good starting point for this?

Good catch

Yeah, funny, they tend to like the sidecar more than being on the back of the bike.

It’s a Street rig. Mostly used for riding long trips and sometimes for rippin twisties. When the failure occurred I was at about 55 or 60 mph on the highway. Headed home from a 2300mile road trip. 40 miles from home it did this. Not heavy revs and a fairly light load in the sidecar (clothes and camping gear) the whole outfit weighs less than 750lbs empty

I already have the JE Pistons kit and a set of freshly bored cylinders. Conrads look like they’re OK. But I want to go through everything just in case. in the meantime. I’m putting this in so that I can take my time to build this motor, right

Well finally took the time to open up my Engine. Now I need to figure out why that cylinder went lean. Had to be over 1150° to melt that piston like that

I’m looking at buying a set of these for my 05 Bandit 1216 build https://www.maxpeedingrods.com/product/connecting-rod-for-suzuki-gsx-r1100w-93-98-gsf1200-bandit-conrod-bielle.html any of you Gents (or ladies) have experience with them?

Except he states he has a 36mm cv set

Turns out it’s only up to 10.8 to one. 81 mm bore. Still curious if I need to do more cooling. Should I be replacing the head stud bolts with new? Any other ideas?

Questions for those who will know. Should I increase cooling with the 1216kit? And with an 81mm bore, will I lose the taper in the bore? Thus needing ring compressor pliers?

Well after about an hours worth of conversation with Dale Walker on the phone. I have a set/kit of pistons on the way. Cylinder is already been shipped to the machine shop to be bored. Cometic head gaskets on the way. Should be around 11 to 1 compression. The machine already has a Holeshot stage 2 set up on the jetting/pipe. This thing ran good before. It’s gonna run really good now
