TC88 chain to gear drive
I am thinking of removing the chain drive and going to gear drive for cams. Every thing i hear about the twin cam is that it is much improved over the evo except in one area the chain drive.
I am no bike mechanic by any means, but in the past havedone some wrenching on autos. For those of you whohave performed this on your bikes, how complicated a job is it. Are there aftermarket gear drives that will work with out changing the stock cams. Do i go with Crane, S&S, Andrews. Any adviceor techenical info onthis subject would be appreciated.

I did my own. It was a very easy job. You cannot use the stock cams, because with a gear drive, thecams turn in opposite directions.
Which cam to use depends on what else you may plan to do to your bike, how heavy your bike is, and what kind of riding you like to do.

The TC engine typically runs 30 degrees hotter than an Evo. I would take a hard look at the 37g cam if I intended to take a lot of heat out of the engine and raise the compression some day. We use the 37's with our stage 2-1/2 with 10.4 to 1 compression, 103-105 torque, 96-98 hp, no pinging, takes 30-50 degrees temp out of the oil.

RE: TC88 chain to gear drive
switching to gears is more complicated than you think. you need a press and need to be very carefull pressing the gears onto the cams. you have to press the bearings in and out of the cam plate and the cams into the bearings. there are special press plates to avoid damaging the bearings.and as long as you are in there, you shouldupgrade all bearings, the cam plate and oil pump so that it will all last the life of the top end, if not the life of the bike.
but if you do all stated above, your twin cam will be the most reliable bike you can own.

You do not have to have a press. I "pressed" my gears on using my bench vise. I used the oven/freezer method to remove and install the bearings. Yes, the bearings should be swapped. No big deal, they come with the cam instal kit. The stock support plate is fine. The stock oil pump is also good enough for the job.

Don't knock it till you try it or at least read up on it. There's always more than one way to skin a cat.
