Triumph Sprint 955i Diary Part 2

 

In the last post I mentioned that the front brakes were pulsing and that I took the bike to Peter Stevens to have the discs etc checked. There was nothing wrong with lateral run-out, the rim or the wheel bearing.  So Peter Stevens agreed to replace the rotors. That was done today and thankfully I now have some feel from the front end while braking into a bend.

A search of Triumph forum posts showed that the problem is not uncommon.  Some guys have had their rotors replaced twice under warranty.  It’s not clear why though. One poster reported his mechanic as saying that the rivets on the floating discs tend to seize so you no longer have the float.  I checked mine and they still flexed.  Who knows.

Meantime, the rear Michie Pilot Road tyre is well worn at 6,500 km.  After last Sunday’s ride through South West Gippsland it was showing evidence of some radical lean angles.  The bike felt squirrelly through some bends and it appears I’d done some of them on the apex of the shoulder.

A better profile of tyre was clearly called for so I headed off to Victorian Motorcycle Wreckers, now in Heidelberg West.  I was hoping for a pair of Pilot Powers but no luck.  A trashed Kwaka of unknown model yielded a pair of near-new Dunlop D208RRs.

Equipped with instructions from the web community of Trumpy grease monkeys, a torque wrench and a 46mm socket, the rear wheel came off fairly readily.  It’s a SSSA so a trip to Redwing brought about the needed fitting and balancing with an offset hub, for $20.

Peter Stevens mounted the front for free while they were doing the discs so now the old dame has some sticky rubber at both ends. 

While in the shop though it appeared there’s a headlight wiring failure on the right side so another trip down is called for.

Mounting up to leave after the front end work, I found the top fork yoke sporting a sticker warning of the need to scrub in new tyres.  Fair enough.  Charlie at Turn One tells the tale of a rider gassing his machine out of the shop with newly fitted tyres only to lose it in front of his mates.  Then kicking a dent in the tank in frustration.  Plastic tank too.  And one of the Staffords reports an FJR1300 rider losing it for the same reason in Bell St.  Serious dent in the plastic of the other kind.

By the way, the Vic Motorcycle Wreckers have a gruesome collection of Hayabusas; the model appears to shear one or both sides of the frame at the headstock (even without having been mono'd). Just bad welding it seems. The shear happens suddenly and you're cactus.  It also appears that Yammie TRXs are prone to frame breakages – the thickness of the steel in the tube frame being a potential weak spot (this is for Tony’s benefit – hope you’re reading the magazine my friend).

Other than those mods, I’ve replaced the original disc horn with an Italian-made electrically powered trumpet imported from the UK and reputed to wake drivers up.  In the inner eastern suburbs it’s not working.  Yes, I know you can’t rely on a horn for safety but my fantasy now is of causing instant heart attack with a dual air horn that plays La Cucaracha.  Not because of the noise but the bad taste.

Well that’s the latest instalment with 27,000 km on the clock.
