Firstly, congratulations on your purchase. You have chosen wisely, the Pit Bike you have bought is one of the best available. We put every conceivable effort into sourcing & specification in order that you will enjoy your machine to the full.
Your bike has been supplied in a crate. This is NOT the same as buying a bike fully PDI’d (Pre Delivery Inspection) bike from a dealer. It is entirely your responsibility to ensure a qualified motorcycle mechanic puts your bike together
correctly. Failure to do so will invalidate the warranty supplied with your bike.
Warranty
Your bike is supplied for off-road use only & therefore the warranty is limited to a 7 day parts only warranty. If you need to claim parts on your warranty, you will need to supply proof (via invoice), that your bike was assembled PDI’d & received its 2 hour service by a qualified motorcycle mechanic.
Guide for Assembly
This document is supplied as a guide and may not be exhaustive. Each machine may require individual attention & therefore ONLY qualified persons should carry out the following:
• Remove outer cardboard packaging
• Disassemble steel cage from around bike removing any ties from the bike and cage
• Remove all accessories & inspect to ensure all necessary parts have been supplied correctly. You should
have the following supplied:
o Invoice as proof of purchase
o Part assembled Bike
o Front wheel assembly
o Handlebars
o Bar clamps & hex bolts
o Front mudguard
o Manual/toolkit – Note professional tools are required for proper assembly
• Remove bike completely from cage base & place bike on work stand
• Lift rear end to suitable angle, pull down rear shock & bolt into lower mounting position
• Remove pad spacer from front brake calliper
• Fit front wheel, spindle & spacers (LONGER spacer on disk side)
• Tighten front wheel & ensure front wheel spins freely
• Fit handlebars
• Pump front brake lever until firm (bleed if necessary)
• Spin wheel to ensure calliper is releasing from disk
• Apply very firm brake pressure to ensure brakes work effectively & that there are no fluid leaks (bleed if necessary). Check fluid levels, top up with DOT4 where necessary
• Fit front mudguard using thread locking compound where required.
• Ensure the correct pressure in tyres 15-20 PSI for off-road
• Loosen rear wheel & adjust chain tension. Find tightest point in chain by spinning rear wheel, there should 15mm up & 15mm down at the longest section of chain with rider sat on bike. Ensure chain runs true & is on top of chain roller. Ensure chain does not foul on rear chain guide (use shims/washer to space if necessary)
• Working from front to rear, ensure all nuts & bolts are tight. Where no nyloc nuts or spring washers are present, ensure thread-locking compound has been used. If none has been used during factory assembly, remove nut or bolt, apply locking compound & re-tighten. Pay particular attention to the following critical safety areas: Wheel nuts, brake calliper bolts (thread lock), Top & rear engine bolts (frame must be hard tight against the engine, use thread lock), chain tensioners, rear shock bolts, triple clamp bolts (yokes), Handlebars, brake/clutch/throttle, swing-arm, front & rear sprocket
• Fully ensure nothing is touching the exhaust system. On oil cooled models, ensure the oil cooler pipes do not touch the exhaust manifold & that the heat protection springs are located on the correct part of the pipe in order that should they touch the exhaust the heat will not damage them.
• Ensure all cables pipes & wiring are away from moving components such as the wheels, use cable ties where necessary
• Adjust tappets. Set engine to TDC, remove tappet covers & adjust tappet clearances ~0.15mm
• Fuel bike & check for fuel leaks
• If fuel leaks from carb overflow – remove carb & adjust float height. Check for any debris which may be blocking the fuel shut-off valve
• Check oil level with bike in upright position using dipstick NOT oil indicator bubble 10W 40 semi synthetic.
• Adjust tension for both clutch & throttle cables.
• Ensure wheel spokes are tight
• Start engine & warm up (using choke if necessary). Set idle speed so engine ticks over comfortably without stalling or racing.
• Test machine ensuring all gears are present & correct & that all controls are fluid & functional. Ensure brakes are working efficiently (bearing in mind that the pads will need to bed in prior to optimum performance)
Engine break-in
Run bike at no more than 2/3’s throttle & do not allow engine to rev to a high speed. Engine break-in should be no less than 2 hours.
2 Hour Service
After 2 hours carry out the following checks & procedures:
• Drain oil & replace with a quality semi synthetic 10w 40 4-stroke engine oil
• Check all nuts & bolts & tighten where necessary
• Check wheel spokes (especially rear wheel drive side) & tighten where necessary
• Re-Adjust throttle cable & clutch cable if required
• Re-tension chain
• Check wheel bearings for any sign of wear of free-play
• Check brake calliper operation & brake pad wear
• Check spark plug gap ~0.6mm-0.7mm
• Check tyre pressures
Riding Tips
It is good practice to carry out the above checks on a regular basis, ideally each time you ride your machine. We advise an oil change after every 10 hours use.
Do not stamp through the gears – always use the clutch
If you miss a gear do NOT stamp into gear from high engine revs
Do not over rev your engine as you may cause damage to valves
Do not drop your clutch heavily, or slip it unnecessarily.
Correct jetting
Your bike has been supplied with jets to suit your engine & exhaust configuration. However, differences in climate & altitude can affect your bikes jetting.
Once your bike has been started & run in take it out for a ride. When you get back home & let the bike cool down. Take out the spark plug and check the electrode; the colour should be golden brown. If it is white, the engine is running too lean (not enough fuel). If it is black (sooty colour) it is too rich (too much fuel). If it is white & black, the engine is VERY lean & causing misfire, which you should be able to detect whilst riding. As your jets are close to what they should be for the UK, minor alterations can be made by adjusting the needle height on your carb.
It is very important to follow this guide to get the most out of your new BULLDOG PIT DIRT BIKE or QUAD BIKE
We hope you have lots of fun on your new bike!
