I did some head work on mine, port and polish, new guides, larger valves, and valve springs. Intake was ported as well to match the heads. Also, the heads were milled for more compression. The heads were shipped to J Precision in Quebec Canada. My 110 is all stock with stock cams. I have a Rinheart Extreme True Dual exhaust with 4 inch mufflers. Also have a Doherty intake. The head work cost me $2300,00 and then I had to dino tune. $350.00 ( using the power commander ) The bike runs so nice compared to stock, seems to be much cooler as well. Making 100 hp and 120 fpt. That chitty thumping noise from the stock intake is gone with the Doherty. ( thank god ) and the power difference is remarkable. It top gear, I can bury the speedo with out any problem. Pulls very hard, and revs very easily. Has some valve train noise but seems to be quieter after the build, and I am using synthetic Amzoil. The fuel consumption is way up to. If I am honking on it I can go through a tank in no time. Kind of shocking at first. I thought I had a fuel leak. If I ride like a pussy, then I can get about 280 miles out of a tank. Love that torque though.
So, If you are going to do the heads to raise compression, do the same things I did to my heads at the same time. The price will be right around what your budget is. Once you are done with that, do your suspension!!!!!! WHAT A DIFFERENCE!!!!!!! I went with Works Shocks and Works Cartridges for the front end. I am telling you, it is THE BEST $2000.00 I have ever spent on any bike mod. What a difference. WOW. I am totally excited to ride now. Love how it feels. How smooth it is, how planted it feels, how it does not dive any more, how I don't get jolted out of my seat, ets ets ets. Cheers.
