+1 on the tune but if the OP doesn't have an oil cooler, he needs to get one. Summers in Texas can see 100*+ temps and getting trapped by road work, wreck, etc. and any air cooled vtwin, regardless of displacement can over heat. I know guys that run two oil coolers. One of the coolers that incorporates fan cooling of the heads would be a wise investment IMHO.

Make sure to check Dat crank run out 🙌

I'd have the bottom end addressed on my 2005 if I were to bump displacement.

Just my two 🪙🪙

hello from germany.i live in germany berlin and have now started the 3rd conversion. I have the tc88 from 2006. I bought the s+s 89cc cylinder heads and the 100cc Sidewinder 4 s+s cylinders and the 585 camshaft. I have converted to carburetor s + s Super G from 93kubikzol. here in Germany no one builds on carburetors anymore. what do you think my setup can work? in addition there is the ignition module from Altmann. Best regards from Berlin to USA the inventor of the Harley Davidson.

I will install the motor in the next few days. I have installed new bearings and painted the motor housing.

I removed the balancer shafts and closed the oil duct to the chain tensioner. it's a try let's see if the engine still runs well.
