Due to a further project on my yellow shed, the existing 853R bigbore kit will be available in November. Kit will include Pistal pistons (R spec) and 916 barrels. Used with the R heads and cams this produced 114 rwbhp. The motor was built 2 years ago and then fully refreshed last winter (crank balanced, RS heads etc). Regular oil changes (Motul 3000V) and increased interval belt changes (start of each season). The barrels where in perfect condition last strip dow, with no wear evident. The motor did 6 trackdays last year, 8 this year and 3 race meetings also. I also have a set of R heads available too. Retail for a new kit is around £1300. Offers invited..................
Ah...sounds tempting....already have an 853r but thinking of a spare engine...got loads are parts etc...how much are you looking for ?
