Information about setting up a Origami B1 Replica Minimoto
When you first get your bike, you will be desperate to get it started and go out racing, but theres several things you should do to your bike before even using it. This will keep the bike in good condition and will give less problems. The bikes themselves arent of highest quality, but being extremely cheap they are fantastic value for money and a vast improvement on a standard air cooled minimoto

Origami Replica Minimoto Modifications
The following things are what we have done to our origami reps to solve problems and increase the bikes performance.
1. Realign Origami brakes.
Most origami replicas come with the brake calipers seized onto their pins. This creates problems with braking, poor adjustability, brake pad wear and can warp a brake disc. To correct this problem, remove the brake calipers from the bike, and grease the pins with copper grease and refit, sometimes some filing of the caliper itself is required to let the calipers float freely. Once reconstructed when the brake is applied the caliper shouldnt move, if the caliper moves its not floating and will be problematic.
2. Fuel tank Heat Problems.
There have been several reports of the exhaust heating up enough to melt the fuel tank pouring petrol on the engine, which you can expect is a bad thing, to stop this happening purchase some aluminium foil and line the bottom of the tank.
3. Fairing Heat Problems.
As the exhaust header is very close to the bottom of the fairing the exhaust will melt thru the fairing, as with the tank line the bottom of the fairing with aluminium tape. The seat fairing can be lined aswell if that starts heating up.
4. Align Clutch.
Most replica origami clutches come unadjusted, we have seen several with the clutches with their clutch springs set to completely different lengths. Remove the clutch bell and adjust the clutch so each spring is of a similar length, after 30 mins running, remove the clutch again and check that the pads are wearing evenly, adjust if not.
5. Cut Origami Bar Ends.
To allow more movement of the bars and to be able to straighten the bars up, remove the bars, cut off excess bar, pop the plastic cap out and refit in the cut bars.
6. Rebuild the Origamis Coolant Cap.
We have found that most origami minimotos come with the coolant cap built incorrectly, and because of the coolant system isnt pressurised and when the coolant heats up, will spray coolant out. To solve this rebuild the cap. Reassemble the components in the following order ( see pic ) and then the system should be pressurised and therefore allow the coolant to get hotter without blowing.
7. Coolant : Dont use the coolant supplied with the bike as when this spills on the track it can create an extremely slippy surface that cant be cleaned, use distilled water with food cooling to show the coolant level
8. Coolant Level : Fill the coolant level to about 1/4 of the coolant tank as this will allow for expansion
9. Bake Clutch To extend the life of the standard clutch it can be baked, ( info coming later )
10. Adjust rear mudguard.
The rear mudguard as standard is far too close to the tyre and will catch , usually throwing the mudguard off, to fix this remove the rear mudguard and slightly bend the mount tabs upwards and refit, the mudguard should be 1 cm away from the tyre. Fit and locktight bolts behind the mudguard mounting tabs to hold the bolts firmly.
11. Padding : Add draught excluder under tank to stop the tank bouncing on the hard metal frame, which stops fuel foaming and better flow.
12. Bolts : Tighten and locktight all bolts
13. Tighten chain : Adjust the rear wheel spacers to increase or decrease chain tension, check the manual for the specs
14. Brakes : Adjust the front brakes so both brakes activate at the same time, check after 10 minutes of riding that both discs are at a similar temperature ( be careful ! ) if not adjust
15. Coolant bottle : Some Origami Reps are supplied with the coolant bottle attached to the wrong side of the mounting tab, if your fairing visor doesnt fit correctly move the bottle to the opposite side of the tab.
16. Tiewrap Brake cable.
The rear mudguard as standard is far too close to the tyre and will catch , usually throwing the mudguard off, to fix this remove the rear mudguard and slightly bend the mount tabs upwards and refit, the mudguard should be 1 cm away from the tyre. Fit and locktight bolts behind the mudguard mounting tabs to hold the bolts firmly.
17. Footpeg bar.
This isnt shown in the picture, but due to the lower frame and peg supports being weak, to strengthen the pegs, a threaded bar can be passed from peg to peg and bolted in place, this will stop the frame cracking or snapping
18. Bounce the bike : When the coolant or water is added there usually are several airlocks in the system. The easiest way of getting rid of all these is to run the bike so its warmed up, then bounce the bike on its back tyre with the bike vertical, and do this several times, then the coolant might need topping up, but the air locks will be gone and should stop oveheating
19. Radiator Mod.
Add a strip of metal from the top fairing mount to the bottom of the origami replicas radiator to stop it vibrating and causing the top mounts to weep , mod supplied by Jim of Bonzia Bikes, thanks Jim.
20. Clean the Air Filter Ok, this seems obvious, but you really need to clean the air filter, drop it in parafin or white spirits for 5 minutes and then leave it to dry. This needs doing every 2 hours of running.
21. Check Clutch Springs The origami replica's clutch will sometimes loosen itself, check all the allen key bolts before every race session so the clutch will not wear unevenly, the springs should be all the same length at all times.
Origami Replica Minimoto Upgrades
1. 74t Sprocket.
For smaller tracks fit a 74 tooth sprocket, this will increase acceleration dramatically
1. Kevlar Clutches.
Probably the best upgrade for your origami replica ! A kevlar clutch lasts about 20 times longer than the standard one and seems to offer better grip. Upgrading to a kevlar is very simple and is recommended
Since upgrading to a kevlar clutch we havent had to adjust the clutch springs in over 5 hours constant running and visibly theres no wear on the clutch. These clutches are extremely hard to get hold of as theres no manufacturer making them. The only way to get a new clutch is to have the existing clutch parts relined with kevlar. So when you go through your first clutch, in about an hour running, contact us, we can put you in touch with our clutch reliner, one kevlar will last many times longer than a standard clutch.
3. Quick Response Throttle : A nice upgrade, to a polini quick response throttle, offers faster response to the bike, specially when cornering and braking and accelerating out of the corners
We have several origami throttle and handle bar grips for sale, if anyone wants to purchases these as they are as new, please contact us.
4. 17.5 del orta carb Adding a 17.5 phva Del Orto carb to these bikes gives the bike an extra 2 bhp supposedly, this will be testing on our bikes shortly and a report written here on the fitting and adjusting and if its worth the upgrade cost
We have several standard carbs and air filters for the origami replica for sale, please contact.
