cutting

I have a UT2 head I am working on with the valve seats for the 26mm intake and 24mm exhaust. I am going to order a 27mm intake tomorrow but am unsure how deep to have the seat honed out. I know to hone the whole seat larger but how far in to the bowl do I go? I know to machine the whole valve...

I have been making gussets and cutting spacers and pretty much cutting most of my metal with a sawzall or cutoff wheel. Some is 1/4" thick. What is everyone using to get straight cuts when cutting stuff? I am debating on what to get next. Band saw? Plasma cutter(but probably not)? Chop saw...

Looks like I'm going to have to shorten a throttle cable I'm getting from OldMiniBikes. Anybody have any insight on what problems might encountered? I've never had to cut one of these, so I'm wondering about how to handle replacing that crimped metal "button" on the carburetor end. Any help would be...

I just bought a used camo baja MB200 last weekend, the one that tractor supply sells. its in like new condition but having a problem when i go to full throttle. it starts right up first pull, idles fine, accelerates fine, mid throttle is fine, but when I go to full throttle after riding around...

What is an affortable saw that cuts and does not spit metal all around. The cold cut saw that is portable, but still sturdy enough to get the job done. Or a portaband with a swag offroad jig for mounting and cutting angles? Thanks for any advice Raf

I never thought of this when I had my intake seat cut to go to a 27mm from a 25. seeing that you cut the seat to go bigger do you need to have the bowl cut as well to actually gain from it all or did I gain anything just cutting the valve seat to go to 27mm. with the bowl being the same size I...

Well, I picked up this bike free from a friend. It had been hacked and re-welded pretty ferociously.... therefore, nothing left to do but cut and weld.:scared: Ive already cut it back apart and gotten rid of some of the mess, but you get the idea..half of the bubble gum welds just fell apart...

My son and I will be heading out to the PRI show in about a half hour. This is the biggest racing trade show in the country. Our Convention Center had to double its size to keep the show here. Before they did that the show occupied the entire center plus had booths lined up on both sides of...

My predator is cutting out at high RPM like 6k. I have been Running 22 low idle and 37 main jet. Nothing seems to stop the problem. Could I be getting vapor lock from the tank. It only seems to be doing it under a load.

as we all know those half size metal Tecumseh gas tanks are nearly impossible to find. And I need one to complete my Bonanza mb250. I started with a regular size Tecumseh tank and took a hacksaw to it and cut the front down . I crimped the metal left on the tank so that the front...

I replace the jack shaft on my gokart recently. I bought a 14 " long 5/8" jackshaft from OldMiniBikes warehouse and some bearings. [ thanks for the fast service and nice quality parts ] I had to find a way to cut threads on both ends of it for it to work. Having the keyway groove on it was...

Anyone out there using one of these torches (Henrob style) DHC-2000 Welding and Cutting Torch Looks like they do about everything a person could expect from a torch. Almost seems to good to be true!

My kids two horse briggs starts easy, idles great, accelerates great but starts cutting out at high, sustained rpms. The engine is stock with a vacujet and points.

How hard is it to cut a key-way in a 3/4" inch shaft on a Tecumseh motor that does not have one for a clutch? Can it be done at home using die grinder or something similar? I'm not looking for it to be perfect, just functional.

In the midst of porting a blue clone head... Is it alright to remove material from the valve guide protruding from the bottom of the intake and exhaust ports? Either cut them flush with the port walls or grind them down some.

Im in the middle of setting up my throttle linkage for my build off. I need to cut the small barrell off the end of the throttle cable i bought. Whats the best way to cut this cable and then stop the cut end from freying out? superglue? can this cable soilder? any tips or ideas would be great.

I was messing around with cutting my throttle cable with regular dykes. Most of the time you will fray the ends when cutting with regular dykes and that makes it difficult to run the cable thru an end or stop. ***Trick: wrap the area you are going to cut with electrical tape 3 times. Cut right...

Has anyone ever used/thought of using a router for woodworking as a milling machine? I’m doing a engine swap on my Doodlebug and I’m planning on drilling out the slots instead of using an adapter plate. Then using a wood-router with a milling bit to clean out the slots. Has anyone ever done...

Hey Guys, A friend of mine suggested that I could cut off every other fin to the 'blower' to cause less drag on my engine. I don't know if this suggestion was such a great one, especially if I've modified my engine to run much faster = hotter. You guys think that this mod could affect...
