Saw this machine outside the KC stadium on Saturday (Hull City's ground for the uninitiated) Superb job the engineering integrity is a joy to behold. I had hoped to collar you for a brief chat and to offer congratulations but by the time I'd finished berating the players and the ref. You were on your way and a just caught a glimpse as you crackled briskly over the flyover

yes it wasnt the best of games and the ref was a shocker, id seen enough and decided to sneak away early, when you see me there again, give me a shout, i like nothing more than talking scooters !
best regards,

set off early on saturday morning and rode the beast to whitby as it was entered in the custom show, had a great day and won best engineering.IMG_1867_zpshr68schx by stephen holt, on Flickr
ride home on saturday was pretty awful gale force winds and rain, i got to about 5 miles from home and the beast made a few funny noises then started missing, i pulled over and stopped, on closer inspection not much compression, suspected holed piston
my suspisions were nearly right, piston had started to detonate, crank has a knackered big end as well, cause running very lean, it was probably the first time ive been able to hold it at full throttle for a long time becouse of the headwind, ive got some bigger jets to go in the carbs. anyway engine is out, crank away for a rebuild, and im doing some modifications to a few things while the engine is out, will post some more pics later,

heres a pic of the piston, the crown is melted rather badly, but the big end bearings did the real damage.

heres a pic of my left downpipe, ive added a groove on both slip joints for a viton rings to stop oil leaking onto the exhaust wrap also ive added a fitting for an exhaust gas temp gauge which i am fitting so i will know if it gets too hot again, a bit late i know, but will protect the engine in the future.

So sorry to see this Holty after all your hard work.

Teething problems... don't let them stop you doing what you're doing

[holty]

its just one of those things, im using the stripdown as an opertunity to alter and add a couple of things, ive fitted the egt gauge into my toolbox, will have a go at wiring it up later, ive also bought an adjustable fan switch so i can set what temperature the radiator fan comes on, also adding a gearchange indicator, its led going to mount it on the handlebars so i will know what gear im in, 6 gears is quite hard to get used to, and neutral is quite hard to find, well was, ive fitted a new gear selector shaft which might help matters, will post some pics later,

heres a pic of my egt gauge

all fitted and working, cant test the probe yet as my engine is not rebuilt yet, the gauge has green amber and red leds around the outside to give you an idea how hot it is and there is a digital readout of the temp in degrees in the center.
ive also got my led digital gear indicator fitted and working, took a bit of messing about, but works great now, will post some pics later.
my crankshaft has been repaired, going to pick it up tomorrow, will start to rebuid the engine in the next few days.

The beast what a machine I admire your skills, for me this is the best engineered scooter I have seen.
