Supposed to get a blaster that is partially tore down. How to check out bottom end?

[Brotato]

Supposed to trade a laptop for this 2002 blaster. He said the piston seized and it needs a piston and ring. Bored .40 and he's already had it honed. Jug is removed and I'm worried about the bottom end. How can I check the bottom end out on this thing?

Also, look at the frame. Some one did a horrible welding job. Is this normal for these frames to break here? Can I remove the nasty weld and have it rewelded? Also thought for added support to have a plate made and welded in underneath. Good idea?

One last thing. He says it's bored .40, so what size(mm) piston am I going to need for this thing? Been a long time since I owned a quad.:-[ If some one could point me towards a decent place to get good parts for this thing I'd appreciate it

WOW I could sneeze a better booger weld than that!!!!! I would not ride it like that.. Yes you should remove some of the booger weld and reweld it, and adding a support plate or any kind of extra support is a very good idea.. I wonder what the hell happened!!! Did you look for any other booger welds or frame cracks?????????

You might want to look at the lower aarms bushings, the heat from the welds might of cooked them..

Welds in a place behind the a arm mounts isn't good. unless it's a really good deal I'd probably walk away. I'd suspect there are more welds that aren't shown and wouldn't trust that frame. Most of the weaker areas are were the frame has cross members that intersect and the swinger bolt mounts on the blaster frames.

wow dude that thing is beat. i dont think i would pay more then 200 or maybe 250$ hopefully your computer isnt worth more then that. i dont know where to start. it looks like some sort or oil block off was put on there:-/, looks like a cheap job. expect that kind of work everywhere. and yes check the frame for any other damage, i bet it was jumped hard. but on a positive note.... it can be fixed im sure, but it will take time and some$$$$$$$ a running blaster could sale for 600$ just my 2 cents and the basic way to check a crank would be to check for up and down movement as well as side to side also check for smooth operation of the bearings. i got ripped off, so i dont want it to happen to any other future blaster rider. 2 cents

that frame is naaasty man, frames can be found pretty common for cheap usually. if you dont use your computer much do it and it can be a fun project, if the computer means alot to ya you might want to pass.

well the laptop is a dell inspiron 1545. I done some trading for it and only have $180 or so into the stuff I traded for it. Guy wants $500 for the blaster.

He said it doesn't have the oil block off plate on it

I probably would for a laptop I don't use too much or have a replacement for.

The frame could be repaired or replaced. Let's be real this is a blaster, not a CR. It's mild steel and easily strippable to be professionally welded and then painted. Even if there are a few spots where it took some damage, it can be carefully repaired (and maybe some frame gussets added) and put right back into service.

As for the engine, .040" is roughly 1mm. You can go up to .090" with wiseco pistons in .010" increments. You'll need some machinist tools to determine the current size and what you'll need to go to OR you can carry it by a machine shop and they can measure it for you.

I JUST bought a wiseco piston kit from woodward specialties who is on this site. He does good business and the prices are excellent. Once you know what size you need to order (either measure it or have a machine shop bore it to the next oversize) he can get the piston right out to you.
