(newb question probably) what size IS my motor?!

[tegwin]

so yeah, I know you guys are all "oh god, one of THESE threads again..."

DON'T WORRY!!!

I do know motor sizes, my virago is a 920cc...


but...I have never seen a M designation to a motor, EVER!!!

my bike is a 2400M(looks like) 4? 2400m4??

edit: a google search shows nothing, except for BMW's haha

Isn't that the oil capacity for the sump- 2400ml ? (2.4 liters).

 

[tegwin]

there is something next to it saying 3000ML


or I might be crazy lol that might actually be the oil capacity...I can't seem to find the motor size anywhere on the motor..mmm..

 

[Big R]

Front of the engine, in between the headers. 652cc's

That 2400 is the oil capacity with an oil change only. It needs more oil with a filter change, and 3000 after overhauling the engine.

 

[tegwin]

ahh ok, This motor is apparent freshly rebuilt, but I am not actually sure about that, we will find out once I get the money to get the stuff I need!


Thanks for helping me find out where the engine thing is, not sure why they hide it like that lol

You've mentioned that before Teg - did the PO tell you that? I'd do a compression test to verify it's within specs in the service manual. If the compression is good then it is a good sign.

 

[tegwin]

not sure if I can do a compression test, the starter is siezed up, he was also cranking the motor over, though very slowly, with NO oil in the case...I put 1.5 qt in the case of 10-30. so unless there is a crank bolt or something that will have to wait

 

[VonYinzer]

If the starter is siezed, I'd have a had time believing it is a "fresh rebuild". I mean, who rebuilds an engine with no kicker, but doesn't repair the starter?

 

[GK]

Not having a go at you mate, but I have to admit I pissed myself laughing when I saw this pic, that is hilarious "my bike is a 2400M" lmao

 

[tegwin]

figured it was some strange euro measurement lol that's where it is on all the other bikes I've tinkered with


but the starter; the inside piece rubs against the magnets and has basically seized it self in place. I was also told it has weisco pistons, which I am doubting, due to not finding anything out there. if I can find a gasket kit for the motor, I may tear it apart and actually look inside, looking through the oil hole the gear set looks amazing, and the crank looks brand new

 

[Big R]

You starter motor probably just needs rebuilt. There are kits available on eBay for about $25 or so.

Wiseco pistons? I've never seen any for the GR. There is another bike that uses the exact same pistons though...... FJ1200 rings a bell? It's odd that another manufacturer uses identical pistons, but if Wiseco makes them for that bike, they should fit the GR650.

 

[tegwin]

umm...yeah, it does...I was going to race a FJ1200 motor haha decided to go V6 though haha

the FJ1200 does has a 13:1 piston set for $400 not sure the GR650 rods could handle that though
