RE: My first bike :D

dtrcruzer · DTR Senior Member

the only reason that would of fell of would be because it did not have the safety locking circlip thing on it that will stop the nut from coming if you can gt a nut on there to get it home if you need to them would probly be alrite

jack_p92 · DTR Senior Member

humm wonder if some little f**ker has taken it off.

need to have a look at an exploded diagram to understand it. Its alrite i work at a garage so its best off there anyway.

Now its dropped half its oil i may aswell put new stuff in so need to order some of that.

Also took my tank off today to have a look at my power valve problem, got the multimeter out and there isn't 12 volts going to any of the wires to the servo when i switch the ignition on...hummm

jack_p92 · DTR Senior Member

found it, is it a washer on the back that folds forwards over the nut to stop it turning? looks like ill have to order one. PITA!!

dtrcruzer · DTR Senior Member

yeah thats the one mate my mate had the same problem he forgot to put it on and pissed all his oil out think he got the nut and washer for about 7quid for yamaha

jack_p92 · DTR Senior Member

nice one :) will order the bits tomorrow unless i can bodge something up at work to secure a nut on there.

craigbulmer · Guru

Dont bodge, not good lol

jack_p92 · DTR Senior Member

ordered the parts today and got a new oil seal just incase.

while its not working thought i would try sort out why its not hitting the power band, took the exhaust off to have a look at the power valve. Does this look right? this is it with the pulley positioned if it where fully open.

Also can i remove the valve without taking the head off? as it looks pretty coked up.

To my eyes that looks like it needs turning round 180 degrees. If the pulley is lined up with the hole, the PV should be flush to the top of the exhaust port. To me that looks like it is protruding in, should not be like that.

Edit: and yup, the PV can be taken out without removing the head. It slides out the side of the barrel.

On the opposite side of the barrel is a cap, take this off and it will reveal the other end of the PV secured by an allen bolt. Stick a drill bit through the hole of the pulley to prevent the PV from turning whilst you take the allen bolt out.

Take the pulley off and the PV can be pushed right out through the pulley end. When out it can be pulled into two seperate pieces as two pins hold is together. It will be fuggin oily and dirty :)

Edit no.2: If you find the allen bolt is tough to remove whilst the PV is pinned, do not force it as you may snap the plastic on your pulley. Instead take the pulley off and use a spanner that fits tight over the end to hold it - the way I did it in fact.

cheers mate :) i was hoping it was upsidedown as hopefully thats why its not hitting a power band. so fingers crossed thats why.

out of intrest tho, why would someone have put it in upside down if it limmits power?

Spartan · DTR Senior Member

Possible did it that way when running it in perhaps to limit power and the chance of blowing a new piston and rings after a re-build, if it's had one in the past that is. Just a thought.

Hopefully one of the other guys can confirm the PV being upside down though as like a second opinion just to be sure xD

jack_p92 · DTR Senior Member

Power valve was upsidedown, also sorted the oil leak on the front sprocket so its running now, off to get another spark plug tonight as its not starting very well.

Sounds a hell of a lot better with the power valve the right way round.

Spartan · DTR Senior Member

Nice one dude :)

Should notice the difference with the PV round the right way.

When I had issues with my bike not starting well, I stripped the HT lead back abit to expose new wire and stuck a new plug cap on the end - this one (there is one listed for RE too, I would imagine no difference tho)

Also cleaned up the contacts for the HT lead, it all helps towards a good spark and it did the trick.

If unsure mate take a quick ganders at this thread, seems like yonks ago now:

jack_p92 · DTR Senior Member

cheeers, put a new plug and cleaned out the air filter and its running better now, except 2 small problems

1/. the small metal pipe coming off the exhaust, before the expansion chamber is leaking, tried to seal it with exhaust paste but it still blowing a bit so need to sort that out.

2/ stopped after work to have a little tinker with my bike and went over a fooking nail :@ scary as hell pulling out onto main road, power band kicking in and the back wheel spinning up and drifting out. luckily didn't come off.

jack_p92 · DTR Senior Member

little update, took my exhaust off, blanked off the hole that goes back to the airbox, dunno what it does tho :/ then painted it black with high temp paint, although its come out a bit grey which is anoying. better than brown rust :)

Also bought a black visor for a brand new helmet i got given today for free :D

and finally bought a cheap alarm off ebay, nothing fancy just connects to the battery but will make me feel a bit securer.

tried to vinyl wrap the swing arm black but i gave up, too fiddly, will try again another time tho.

jack_p92 · DTR Senior Member

Made a template for a tail tidy that im going to cut out of some allu at work tomorow and ordered one of these little LED lights for the number plate.

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=360288093571&ssPageName=STRK:MEWNX:IT#ht_1110wt_1139

.
Going to mount it further forward under the rear fender to make the bike look shorter.

Also thinking about smoothing off the rear fender light and mounting an LED one at the back scene as no one makes a smooth one for the RE.

DT-R_bradders · Guru

jack_p92 · DTR Senior Member

Pre bodge template to get the right shape:

Final template, just need to get the mounting holes to the frame right.

Also my helmet for now, got given as a gift

DT-R_bradders · Guru

Lookin gd m8 wats with the 90deg flaps on the sides they for the indi mounts?

jack_p92 · DTR Senior Member

the flaps on the side are to mount it to the frame. There are 2 bolts already there that hold the back piece of the frame on (bolt 22/23 on this pic) as there on both sides

jack_p92 · DTR Senior Member

tail tidy is done, didn't get any pics of me making it but heres it fitted. Need to move the number plate a bit higher up, also the L plate caught on my tyre and cracked the bottom of it off, so bent the number plate out a bit more like it is in the pic.
