THINGS YOU NEED TO KNOW

-

Blown head gaskets: The weak point on an otherwise bulletproo­f motor. The rear cylinders are where trouble is likely to rear its ugly head. V4s run warm anyway, so avoid town work on hot days. Replacing the gasket is a pig of a job, too. Treat your coolant system to regular flushes. Other than that, the V4 lump is an engineerin­g masterpiec­e.

Reg/recs: A tedious and all too well known issue for VFRS. Not a case of if the reg/rec will throw in the towel, but when. If you’re buying an RC24, ask the seller how old the reg/rec is. If it’s ancient, expect trouble and budget around £110 for a replacemen­t. Alternator­s also have a habit of failing at higher mileages.

Rotten pipes: Another perennial VFR issue. There’s no collector box on the RC24, but rot – especially on UK owned bikes – still spells the end for many a system. OE replacemen­ts are virtually impossible to find. A tidy used system, or pre-owned stainless Motad may be the only option if you want standard(ish). There are tasty race-style systems available, like Hindle, if originalit­y isn’t essential.

Carb trouble: The Keihin carbs are generally robust, but issues with bikes that have done a lot of low speed town work or time on idle are known. Needles, emulsion tubes and float valves can all fret. If you’re going to store a VFR for a while, empty the carbs of fuel first – modern, ethanol rich petrol can cause havoc, corroding jets and gumming up anything it comes into contact with.

Tyre choice: Early G/H models are at a disadvanta­ge running the 16/18-inch combo. Only Bridgeston­e list a tyre in the OE 110/90 x 16 size (BT45). Avon offer a Roadrider, but only in 120/80 x 16 size. From ’88 (J model) tyre choice is better thanks to the 17-inch front. The later wheel can be retrofitte­d, but it requires a complete front-end transplant.
