Teach me how to port a chainsaw

[Trx250r180]

Like the tittle said ,i would like to start a serious thread on this . I have had several loggers hear about my hopped up saws ,and they want me to mod theirs ,i have turned down 6-7 jobs now and gave references to other builders ,but they need them for work ,and do not have the time to send them off and wait to get this service done ,What kind of grinding tools do i need and how do i come up with good #s for a worksaw that will be wearing a longer bar ?

I just want some good work saw results ,no squish cut stuff just a little angrier running than stock ,i am not into racing.

Have you done any port grinding at all?

Only on atv jugs,lot more room in there for bits though,i had copied a couple different ideas from other guys work and came up with a couple good runners ,my air die grinders are too large for chainsaw work ,i will need something smaller

So is the hammer and chisel for widening the ports or for getting the piston out of the cylinder after you already ported the saw?

 

[pioneerguy600]

A lot of the guys found Dremel flex shafts and bits were good enough until they got into upper transfers. A dremel with stacked up cut off discs can and will do a fair job on raising the upper transfers, the longer extended bits about 3" long will do any of the intake , exhaust and lower to upper transfer port work.

 

[pioneerguy600]

There are lots of more expensive grinders and tooling out there, just depends on how far you want to go and how much you want to spend.

The first two saws I plan on doing are a husky 350 and jonsered cs2159 they both have plates over the transfer ports that can be unbolted so I'm going to buy a Dremel tool to do those and if I like how they come out I'm going to pick up a kit from cc specialty tools to do the rest. As matter of fact I'm really close to starting on my husqvarna 350
