buying engine help

[brendonv]

There all the same engine. Theres tons of em on ebay. Just bid and get a good one for 220. That one with the battery will go for like 280 i reckon.

well the excact same type sold for $110 the other day, so il watch this one.

lol, i rang a bike wrecker n they wanted $1200 for an old honda cr125 engine than needed rebuilding, lol ok bye i said. cant afford that.

 

[brendonv]

dang thats expensive. Well honda clone is lookin good then. **** 110AUD? Dam i gotta get a deal like that. I can afford 150 for a clone atm but not 250. If i can pick one up for that price ill grab it.

 

[jacko101]

it sux that shipping is like $50 too, oh well its probly worth it.

 

[brendonv]

yer, there a good engine. Just the shaft is a bummer but nothing a bit of sand paper cant fix.

Well, if it has a gear reduction box, you can just slap a cent. clutch or TC on it. But you could use either a jackshaft to bring the rpm's back to normal, or just run a belt tensioner clutch.

Also, theres 8 days left to that auction, so dont expect it to stay at 99c.

No need for a jackshaft, just get a 30 tooth sprocket.

The clutch wont fully engage, the reduction box will bring the normal redline of 3600 rpm down to 1800, most clutches start to engage at 1800-2200.

The whole bike goes for less than that, running.

thanx but now im confused lol, so i cant run a 12-60 ratio sprockets

 

[EagleTalons]

Use lighter clutch springs. a 12-60 ratio is 1:5, but with the reduction it is now 1:10.

 

[Kaptain Krunch]

in my opinion, a belt tensioner style clutch would be much better, no fussing with lighter springs (which would be hard to find for your average cheap clutch), and a belt tensioner clutch would grab much better than cent.

 

[EagleTalons]

Well true, a belt style would be easier at this point...what do you suggest for a clutch on an airplane engine I found?

Junk that thing and get a sled or mc engine

 

[brendonv]

why u buying the one with the reduction box? That ones ****, get the other clone without it. Its cheaper and sold by the same ebay company.

 

[toofarnorth]

the reduction unit should come right off and you should be left with a 20mm shaft, at least that's the way it is with my gx160 mine has a built in wet clutch though so no need to remove.

 

[Kaptain Krunch]

Yours has the wet clutch and reduction box, most ones with just a reduction box have bad crankshafts. Normally the end of the crank is actually the gear.

Yeah you're probably right, I didn't notice how slim that reduction unit was if it did have a 20mm crankshaft it'd probably be pretty stubby. The engine is still worth watching though sometimes those oddball setups can go cheap, then it would just take a little ingenuity to get it to work.

 

[Kaptain Krunch]

Like i said before, a belt tensioner clutch would work fine. I was gonna do that with an 8hp that i had with a reduction box.
