Stock bore for the XL600 is 100mm.

101 is an overbore kit.

Honda overbore kits are 100.25 and 100.50

If you are thinking big bore, the largest I know of without doing major mods and using still using original sleeve rebored is the Wiseco 102.4. I ran one in my XL for many miles and years with no problems. I ran it with stock cam and springs etc. It made a noticeable difference in power, with no changes in mannerisms. As they say, there is no substitute for cubic inches.

Hi. Im in the process of a rebuild on my '86 and have purchased a Wiseco 101 11:1 kit. With the higher compression i was wondering about the need to look at jetting to get the most out of it.
I live at sea level, temperature range about 5 - 30 deg C. The jetting I have is 108, 65 main carb and 105 in the other.
Any advise would be appreciated so I can do it while the beast is in bits!
Thanks

If you dont change anything airflow-wise [ filter , airbox or exhaust ] your bike will run richer due to the increased compression.

Is 101.00mm the stock rings for the 83 600r?

Thanks

Hey, we all started out ignorant. When I was born I knew nothing. Now at 67, I know even less!

I live near sea level too, but have much larger jets in my 87 XL. 125 primary carb, 118 secondary.

Bigger bore usually doesn't need drastically different jets, but yours sounds too lean to start with from my experiences.

Hmm, I'm a bit more conservative...I started off with nothing, after careful budgeting, I found that I still have most of it left

And higher compression will make a lean mixture more likely to ping.

Thanks all, for the replies I guess I will need to research the thread for some more on jetting . It sounds a bit of a mine field !!

I wanna rejet mine but I don't know anything about it. I'm pretty sure I can get more power out of this thing if i changed the jets

RFVC600R · 02-24-2013, 04:21 AM

So basically I go WOT and shut the engine off and pull the plug for a reading?

Mine kinda looks like this when I check/change it once in a while

Anyone knows where I could find the white seal wich is installed on the edge of the fuel tank on a XL600 LM?

Many thanks,
