CB750 k1 836cc kit

[750rideruk]

I am looking to rebore my K1 engine and am considering using an 836cc kit from Japan. In the details they state the piston diameter of 65mm. The O/D of the cylinder spigot is only 68mm and I think this may be a bit thin after reboring. Anyone got any experience of using these kits?

If you check on the US forum plenty on there have used the cruzinimage 836 kit with no major problems I beleive, other than some deburring required from memory. Certainly Hondaman on there has used them and if its good enough for him....

Its OK but you need a VERY good reboring firm to do the job as if the liner cracks its totalled

Bryan I'll be fitting an 836 kit to a project later in the year..know any very good shops for the rebore? Also, do you undertake engine builds yourself?

[Bryanj]

Re builds yes, and I do know a shop if he will take it on but it was £25 per hole plus vat!!! and its a long way to take it out.

I will be at work Sunday night if you want to ring my mobile after about 8pm 07795162623.

Thanks Bryan - bit tied up sunday night but will drop you a text to arrange a time. It's a 750 k2 rebuild I'm looking at. James
