High(er) Mileage GPs?

Postby mort9555 » 19 Mar 2018 21:04

Hi All,
This post is just an inquiry really as I'm intrigued to know of any higher mileage GP's that are out there and used regularly. I have an 09 bike, had it from new and now has 41k miles on it. Just for general info.....a bit of history;

Up to now, I've had no mechanical traumas and which surprises me immensely. It had a new ECU and speedo head at 5k miles under warranty and which cured the 'fuel starvation' scenario they used to suffer from. Also had the dip beam bracket mod (grinder courtesy of the late Alex at NLM) to cure the bulb blowing/contact with bracketry issue). Had rear wheel bearings at 20k miles and a speedo pickup at same time, damaged due to too much aggressive cleaning in the area. Also needs a new cold start/fast idle valve currently but I'm saving up for that as I'm sure it'll be immensely eye-watering come the time. Also just changing the original battery as 9 years is long enough I reckon.

Checked the timing chains/tensioners status at 35k miles out of interest. Tensioner plungers were approx 50% extended. I plan to change the chains (same as Yamaha WR400 items!!) at 50k miles. Bike has had Motul 10W/60 FS oil every 6k, filter and strainer clean as per the book instructions. It uses no oil between changes, fuel is about 37mpg. It had a BSD remap with Corsaro map and lambda deletion in 2013 and which made the engine a completely different animal. This remap made the emission-restrained motor a bloody riot......and unmistakably italian.

It's done 80% of its miles abroad, two up and fully loaded with factory panniers and H&B rear rack. Ohlins was rebuilt at 35k miles. I have a set of 2006 WP super duke forks/yokes going on now as they are fully adjustable and quality items. The original Marzocchis belong on a pushbike! I pulled the front footrests up 3 inches and slightly back before they were too short to be useful. Running Dunlop Roadsmart 3's front and back with tubes and still on the original brake pads front and back. The wife reckons it is THE BEST pillion perch by a long shot and we've had a few bikes over the years. Only issue is the mountaineering aspect of getting up there in the first place.

I'd be really interested to hear from any fellow GP owners and their experiences with similar mileage or more if there are many of you out there?

Hello Mort

After a Corsaro with 18k miles changed to a GP and now 40k miles also. NO problems so far but the speed sensor (changed with a Ducati unit) , no oil between changes, a remap with lambda delete and +500rpm. Cat delete and two exhausts. Great ride indeed!. All the time with luggage and my wife.

I am very interested how you pulled the footrests up and back. Could you send any photos please?

Interesting to see you have clocked up serious mileage without any problems other than the usual which I have also experienced. You mentioned a cat delete, have you bought a link pipe or is that just the chip, I have been looking to remove the lump for some time and have even gone as far as a custom fab system, any thoughts from other owners.
The WP forks sounds like a great mod, are they the same OD as the morini are you using the same 2pot brakes etc.
Very interested to do this as it is very harsh over bumps as stock.

Still love this bike and it never ceases to put a grin on my face every time I ride, not many bikes I have owned have done that. WIll need tyres chain and sprockets soon so will be keeping it for many more years to come.

I hope to be out and about this year on the GP so if anyone fancies meeting up
Best wishes steve

Hi rrey,
Thanks for offering your experiences. I'll get some photos together and get them uploaded.

With the footrest pos'n change.....I basically drilled through the alloy mounting plates and machined some mounting bushes for the footrest location bolts with an angle on them to mate them to the mounting plates. The mounting plates run at an angle as you probably know. I'm still refining the gear lever design as the gearbox certainly needs a very positive hoof to function. So the gear lever pivot/reaction force was a bit of an issue but I've got it now. I made a pivot bolt & brass bushes to carry the original gear lever and a longer connector rod to get the lever adjustment as it fouled the clutch slave cylinder on the up-shift. The rear brake pedal has not moved, I just used 'Polymorph', a reuseable polymer (from Maplins....but they've gone now) to create a 'taller' brake pedal foot pad. It probably sounds a bit 'heath-robinson' but it works and gives a more natural position than the standard low peg/extended leg set-up. I'm 5'11'' and suits me but that's me. Saving a fortune on boots!

And, Hi Painter,
The WP forks have the KTM top/botton yokes with them. If I can't find some h/bar mounting clamps off a KTM (got to be reasonable money!) I'll make a set. I'm going to fit Renthal bars also. I guess I'll also need some sort of riser arrangement to lift the bar mount height to clear the tank recess. The measurements for callipers/forks/discs look pretty damn good as far as i can see so all original brake kit will be going back on. Only things I need to machine up will be bushes for the front wheel spindle as the KTM spindle mounting bores are considerably larger. The front end is a real dud with Mazzos on, this mod should be night&day better. I'll let you know when I get it done and drop a few shots on here.

And finally.....An issue I forgot to mention was the aggro with the Marelli idle control valve which, up until last year was doing my yud in. It's party piece was a 2k tickover all the time when the ambient temp was below 10/11 degs. Real irritating! And then, when the ambient temp became higher, the bike had a very annoying habit of stalling in the most awkward circumstances. Fully loaded and 2-up, this was indeed hernia territory! So..... I blanked the air feed pipes of the valve in the airbox, left the connection attached to keep the diag light off on the dash and turned the throttle stop screws 1 turn to get a tickover thus operating on the butterfly position, not via the valve. It worked a treat. Cold starting was a case of taking the slack out of the throttle cable and pushing the button and holding the throttle in this position for about 30 seconds. That was it.....no stalling and no excessive idle.

Cheers to both

Sorry chaps, sent the last mail without finishing it...........

With regard to de-catting ...........I inadvertently put a gallon of diesel in my Morini about 10 months ago. God only knows why but the absent mind is a dangerous thing! The story is painful but in a nutshell, the bike ran a little subdued for quite a few miles until it then wouldn't run on the rear cylinder (blocked cat). Subsequently, while trying to get back home, the catalyser partially disintegrated and went backwards which caused a substantial bonfire in the silencer. The silencer got that hot that the under tray started to bubble. To remedy, I had to cut the collector in half and remove what was left of the cat unit. It's only tack welded in and the whole job when the exhaust was off took about an hour. The mixture doesn't look unduly wrong so I'm leaving it as is.

I think you have it spot on Steve.........this bike never fails to bring on a grin. It's certainly a part of our family and will be until I can't actually get on it any longer.

Steve, whereabouts are you based?
